We report an entanglement generation experiment that utilizes a silicon waveguide. Using spontaneous four-wave mixing in a 1.09-cm-long silicon wire waveguide, we generated 1.5μm, high-purity time-bin entangled photons without temperature control and observed a two-photon interference fringe with >73% visibility.
